前言自Laennec发明听诊器以来,能够由肺、胸部用听诊器诊断出呼吸系统疾病。但是基本上都是凭医生的诊断经验来评价和判断的,没有统一的标准。尽管试用了用听诊器得到的客观结果记述呼吸音,但还没有利用声学进行呼吸音的分析。近年来,提出用时间轴扩展波形对连续性、不连续性罗音新的分类标准。本邦根据振动波形提出了间质性肺炎的不连续性罗音特 Introduction Since Laennec invented the stethoscope, it has been possible to diagnose respiratory diseases by using a stethoscope in the lungs and chest. But basically all are evaluated and judged by the doctor’s diagnostic experience, there is no uniform standard. Although the objective results obtained with a stethoscope have been tried out to describe the breath sounds, no analysis of the breath sounds has been made using the acoustics. In recent years, a new classification criterion of continuous and discontinuous rales using time-axis extended waveform is proposed. The state according to the vibration waveform proposed interstitial pneumonia discontinuity Luo Yin special
